摘　　要：以COMSOL Multiphysics多物理场仿真软件为载体,建立激光与碳纤维相互作用的温度场和应力场,研究碳纤维受激光烧蚀后的表面温度场和应力场特性。结果表明:对于激光的周期性往复烧蚀,温度场和应力场均呈周期性变化。不同激光参数下温度场的影响主要表现在温度高低和升温速率,对应力场的影响主要表现在应力大小和增量。该仿真研究对复合材料激光表面处理有一定参考价值。The temperature field and stress field of the interaction between laser and carbon fiber were established based on the COMSOL Multiphysics software,and the surface temperature field and stress field characteristics of carbon fiber after laser ablation were studied. The results indicate that temperature field and stress field show periodic changes in the laser reciprocating periodic ablation. The effect of different laser parameters on temperature field is mainly reflected in temperature and temperature rising speed,and the effect on the stress field is mainly reflected in stress size and increment,respectively. The simulation research has certain reference value for laser surface treatment of composite materials.
